Quilting Suggestions?

I just finished basting this quilt top and now I feel sort of stuck. I can't decide how to quilt it. I initially thought about straight line quilting it, but the blocks are pretty big (about 15") so I'd have to do more than just echo quilting the seams. Maybe a design? Random lines?

Or maybe free motion quilting? All I've ever done is a meander/stipple. I thought about loops, but then I'm not sure if I should do them randomly, from side to side, from the centre out? Ack, decisions! I'm usually pretty decisive, but not this time :)

Any and all suggestions would be welcome!

Thanks and have a fabulous weekend!
